Specification of Letters Patent.

Patented May 28,1912.

Application filed October 14, 1911. Serial No. 654,591.

siding at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to stoves and more particularly to hot-air heating stoves.

An object of the invention is to improve the construction of the stove so that a thorough circulation of air may be had between the fire-pot and the outer wall of the stove, a portion of the air heated in this space passing out into the room or compartment from a point about at the top of the fire-pot, the remainder of the air heated within this space being arrested and carried downwardly through a draft throat to enter the fire-pot from beneath the grate.

Another object is to improve the construction of the stove so that cool air will rise from adjacent the floor and travel upwardly between the base and theash-box or comp artment and continueupwardly between the fire-pot. and the outer wall of the stove, at which point it becomes heated from the influence of the fire within the fire-pot and then travels outwardly into the room or compartment at a point about even with the top of the fire-pot, the heated air being di rected downwardly in its exit from between the fire-pot and the outer facing of the stove.

Another object is to produce a stove of novel form of construction and which will have athorough circulation of air between the interior and exterior walls of the stove and one in which the parts will be so constructed and connected together that the plated or ornamental parts will be protected from the heat or current of heated air.

Other objects and advantages will be hereinafter set forth and pointed out in the specification and claims.

In the accompanying drawings which are made a part of this application, Figure 1, is a perspective view, parts being broken away,

Fig. 2, is an enlarged vertical sectional view through the lower part of the structure, Fig. 3, is an enlarged sectional view on line 33 of Fig. 2, Fig. 4, is a view similar to Fig. 2, taken at right angles thereto, Fig. 5, is a sectional View on the line 55 of Fig. 1, and Fig. 6, is a slightly enlarged fragmentary sectional detail, showing the manner of removably securing the ornamental guard plate. v

Referring more particularly to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 represent-s the base of the stove which may be of any form desired and 2 the ash-box or compartment within the base 1 and spaced therefrom at the opposite sides and the rear. The base 1 is positioned upon and supported above the floor by the legs 3 which are connected in any suitable manner and have the flange 4 over which the right angled lower edge 5 of the base 1 is engaged at the rear and the two sides of the stove. At the rear and the two sides of the stove, the base 1 has its upper edge bent inwardly as shown 6 and then upwardly as shown at 7 to provide the horizontal seat and the flange respectively. The

outer wall or casing 8 has its lower end resting upon the horizontal seat 6 and against the outer surface or side of the flange 7, at the rear and the two sides, while the front portion of the lower edge of the casing 8 is extended downwardly and rests upon the seat 9 of the horizontal portion 10 of the ash box or pit 2, said casing 8 also resting against the upwardly extended flange 11 carried at this point upon the horizontal portion 10. The seat 9 and flange 11 are inwardly of the front of the stove and a door 12 is located in the front of the base 1 and opens into the ash box 2, said ash-box and base 1 connecting at the front of the stove, as will be readily seen.

Positioned upon the base 1, at the front of the stove and outwardly of the casing 8 is the down draft throat 13, which may be of any form desired, but is preferably cylindrical or oblong in cross section and provided with the outwardly turned side flanges 14 adapted to be secured to the outer casing 8 in any well known manner, said flanges extending practically the full length of the throat 13.

Extending upwardly from the horizontal portion 10 of the ash box 2 is the circular ring or flange 15 which is enlarged or flared at its upper edge to provide the annular channel 16 upon the opposite sides of which are the vertical parallel flanges 17 the purpose of the channel 16 and flanges 17 being to support the lower end of the sectional fire-pot as will be presently fully described. The upper edge of the sectional fire-pot is supported by a specially constructed ring between the lower portion of the stove and the central or upper portion thereof, as will be later described in detail.

The upper circular edge of the outer casing 8 of the stove is turned outwardly in a horizontal direction to form the rest flange 18 upon which rests the smaller annular portion 19 of the ring 20, the smaller portion 19 being connected with the ring 20 by the spacing straps 21, thus forming openings between the straps, the purpose of which will presently appear. Extending upwardly from the ring 20 is the circular stop flange 22 and outwardly of this flange the ring 20 is provided with a plurality of openings 23 for the reception of the lugs 24- of the orna vmental shield 25 which is preferably formed in sections and removably secured over the ring 20. The ring 20 may also have the outwardly directed spacing ribs or lugs 26 for holding the sections of the shield 25 spaced from said ring and thus prevent the heated air from reaching the shield 20 and tarnishing or otherwise injuring the same.

The sectional fire-pot is formed of the vertically positioned interlocking male and female sections 27 and 28, respectively. The male and female sections are arranged alternately. the straight edges of the latter fitting within the turned vertical edges of the former. The sections are preferably arranged with a very narrow space between the face and the sides thereof to allow the products of combustion to reach these side spaces of the sections and thus more readily keep the air passing upwardly within the.

sections. The lower ends of the sections are open and communicate with the space between the base 1 and the ash-box 2, thus allowing the air to travel upwardly through the sections, it being understood that the sections are arranged with their upper sides against the outer casing 8 of the stove. The construction of the sectional fire-pot is not an essential part of this invention, but it is necessary for the upper ends of the sections to extend above the outwardly turned upper edge of the casing 8 to allow the air traveling upwardly through said sections 27 and 28 and being heated in its upward travel, to

pass above the casing 8 and then be directed downwardly between the connecting straps 21, the air being directed downwardly by means of the closed upper ends 29 of said sections and the upper ring 30 having its lower edge resting upon the ring 20 and against the rib 22 extending upwardly from said ring 20. The lower opened ends of the sections 27 and 28 are bent horizontally and then downwardly, as shown at 31 for engagement within the circular channel 16 while the upper closed ends thereof are provided with the upwardly extending ribs 32 which are adapted to be received within the circular channel 33 in the under side of the horizontal portion 34 of the upper ring 30 when said ring is in position upon the ring 20. The horizontal portion 34- of the ring 30 is also provided with a similar channel 35 within its upper face for the next section of the stove casing, as will be readily understood. It will be understood that the portion of the stove above the ring 30 may be of the horizontal portion of the ring 20 and the connecting straps 21 and above the upper end of the down draft throat 13 is a down draft controlling slide 36 having the bent arm 37 the free end of which is reduced and extended through a suitable slot 38 in the ring 30 and controlled by means of the handle 39 pivoted thereto. By properly manipulating the handle 39, the slide 36 may be moved above the upper end of the down draft throat 18 to regulate the amount of super-heated air passing from the upper ends of the air channels in the sections 27 and 28 of the fire-pot, downwardly through the down draft throat l3 and into the ash box 2 to travel upwardly through the grate and thus assist in the combustion of the combustible gases within the combustion chamber or fire-pot.

It will be evident that when the fire is first started or fresh coal is placed thereupon, the burning or consuming of the combustion gases may be greatly facilitated by manipulating the pivoted controlling handle 39 to move the slide 36 from upon the upper end of the down draft throat 13, thus permitting a large quantity of the super-heated air to pass downwardlythrough the throat 13 and into the ash-box 2 to rise through the grate, as just described. When the fire is burning brightly, however, the slide 36 may be so positioned over the upper end of the down draft throat 13 as to prevent the super-heated air from passing down the throat and into the ash-box 2. As the greater portion of the heated air passes from within the sections 27 and 28 to the room or compartment, between the connecting straps 21, and is deflected by the lower ring 20, it

will be evident that the room or compart- Inent will be thoroughly heated, especially adjacent the floor.

' It will be understood that the smoke, etc, from within the fire-pot may escape through a suitable pipe connected with the upper portion of the stove or it may be carried off in any preferred manner, this point being determined by the pipe at the upper portion of the stove.

The details of construction of the lower port-ion of the stove may be varied as desired, but the circulation of air must be the same, said air passing from adjacent the floor, upwardly between the base 1 and the ash box 2, into the sections 27 and 28 of the sectional fire-pot and outwardly at the top of the fire-pot sections and then downwardly, the greater portion of the air upon leaving the fire-pot sections beingdeflected by the rings 30 and 20 and passing between the connecting straps 21 into the room or compartment, the remainder of the air being directed downwardly through the down draft throat 13 and into the ash-box 2- Owing to the comparatively small number of parts employed in the construction of the lower part of the stove in accordance with this invention, and the simple formation and interlocking engagement of said part-s it will be evident that a strong connection may be had between the various interlocking parts and that a strong substantial stove of compact form and light in weight will be produced and one which will be eflective in the performance of its duties.
